摘要：

Facile photorefractive (PR) composite films were prepared. As evidence of PR effect of the PR composite films, two-beam coupling (TBC) experiment were carried out at 633 nm wavelength. Interestingly, strong energy transfers appeared under zero external electric field (E-ex). The highest TBC gain coefficient is up to 230.32 cm(-1). The TBC gain coefficient increases with the increase of photosensitizer within certain range. The probable cause of PR effect under non-external electric field were proposed.
